IMPROVEMENT IN SALT-KILNS.

Specification forming part of Letters Patent No. 10,564, dated February 28, 1854.

f 0 @ZZ whom it may concern.'

Be it known that I, JonN P. OONGER, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Making Salt; and Ihereby declare the following to be a full and clear description thereof, reference being had to the drawings herewith presented, which drawings constitute a part of said description.

The nature of my improvementconsists in the construction of a kiln with small fires at each end, so as to 1apply the lire near to the boilers, having but a short arch over each lire, and conducting the ilues immediately to the kettles.

The common modev of making salt is to have a long kiln, say, 011e hundred feet, (more or less) with one large iire at one end, and an arch of brick extending along between it and the kettles, to prevent melting the kettles, whereas I have a short arch at each end just over the iirc, and then conduct the flue direct to the pans. I also have a cistern of water placed above thekiln through which the flame is conveyed with tubes, for thepurpose of heating the water before it comes into the pans.

In the drawings, Plate 'l is a View of the kiln. A is the front side. B B are the kettles. O is the arch supporting the kettles. E is the nre-Hue; D, the chimney, F, the tubes passing through the trough or oistern G, furnished with holes I, to draw the water into each pan.

Plate 2is a View of the same, having the top removed in order to show the interior arches, L, inside walls, K, and center wall, M, eX- tending the length of the kiln. N is a hole to let the heat pass under the kettles.

Plate 3 is a sectional end View, showing the v arch P, the grate R, ash-pit T, and chimneysl I am aware that tubes have been used for the purpose of heating lwater for other purposes ytherefore I do not claim the invention of tubes, but the application of them to the making of salt I believe has never been made before; and by means of my new kiln I am able to make more in any given time and with a vast deal less amount of fuel.

What I claim, and desire to secure by Letters Patent, is-

rIhe arrangement of a salt-kiln having two small iires with short arches over the grates at each end, and the lines thereof` meeting in the middle of the kiln and passing into tubesleading through the feedtrough, placed immediately above and along the kiln, in the manner and for the purposes set forth.

In testimony whereof I hereto subscribe my name in presence of two Witnesses.
